Product details

Mounts on standard DIN rail or with screw fixing, any orientation. Installation depth is 92 mm — that's deeper than the 70 mm of the 5SP4380-7 sibling, so if you're swapping into a panel that was laid out for the shallower unit, check the gland plate clearance and wire bend radius before committing. IP20 with connected conductors is the norm for a DIN-rail breaker; the sealable feature lets you lock the handle position for isolation lockout/tagout.

Rated for AC/DC voltage, with a maximum of 440 V AC. The supply frequency is 50 Hz. Mechanical service life is 20 000 switching cycles typical.

Frequently asked questions

What is the breaking capacity of 5SP9320-7KC47?

50 kA at 400 V AC per IEC 60947-2. That is the industrial standard rating, not the lower EN 60898 figure used for residential MCBs.

Will 5SP9320-7KC47 drop into a panel designed for 5SP4380-7?

The 5SP9320-7KC47 has a 92 mm installation depth versus 70 mm on the 5SP4380-7. Both mount on standard DIN rail with screw fixing and share the same 4.5 modular width units, so the footprint on the rail is the same, but the deeper body may interfere with wiring ducts or the back panel. Check clearance before ordering.

What is the temperature range for 5SP9320-7KC47?

Rated for -40 °C minimum to 75 °C maximum ambient. Periodic exposure up to +55 °C at 95% humidity is allowed.

Where can I buy 5SP9320-7KC47?

Sourced and quoted to order against an RFQ through independent distribution channels. Current pricing and availability are confirmed at quote time.

What compliance documentation is available for 5SP9320-7KC47?

The part carries IEC 60947-2 certification for its 50 kA breaking capacity. It is halogen-free and silicon-free. The manufacturer provides standard RoHS and REACH declarations; specific documentation is available on request.
